Significance of your results: Titanium is also commonly anodized, but does not need to be dyed to achieve colored surface layers. Instead, the color comes from thin-film refraction within the oxide layer - the color is characteristic of the thickness of the oxide layer. Ti²+ (aq) + 2e-Ti (s) E° = -1.60 V TiO₂ (s) + 4 H+ (aq) + 4 e− = Ti (s) + H₂0 (1) a. What is the half-reaction at the anode for the anodization of titanium? E° = -1.076 V b. Under standard conditions, what is the smallest potential you would need to provide in order to anodize titanium?
